in the first place, without brush and commutator, is limited to the traditional dc motor high speed large capacity motor development of several factors, such as the commutation spark, the mechanical strength of the commutator and brush wear problem by changing the conditions of commutation method are well solved. No sliding contact also solved the problem of the commutation spark, make its can be used in explosive environment. Brushless structure and improve the efficiency of the motor itself has no excitation loss and loss of carbon brush, eliminating the multiple reduction consumption, comprehensive energy-saving rate can reach 20% ~ 60%.
second, can run for high power at low speed, can save the reducer direct drive big load; Excellent torque characteristics, medium and low speed torque performance is good, big start torque, small starting current; Stepless speed regulation, wide speed range, overload ability, etc.
again, and turbulence shock resistance, low noise, little vibration, smooth operation, long service life.
brushless motors are widely used in
has these advantages, the brushless motor is widely used in the production and living.
with brushless motor production design and the control level of ascension, it is more widely used in various fields. In general there are three main purposes: continuous load and variable load application, positioning applications.
to aerospace mechanical arm control, gyroscope and steering gear drive, or oil pump in the field of automotive industry control, electric controller, engine control, such as small to vacuum cleaner, mixer, electric hair dryer in daily life, cameras and household electric fans and other household electrical appliances, or digital camera, laser printers, photocopiers, fax machines, tape recorders, LD drive DVD and shredders and other office equipment, can see the figure of brushless motor.
there is also a must carry, applications are of concern in recent years, unmanned aircraft, aircraft. Big xinjiang aerial drones success system spread to ordinary families, people began to more and more attention to this emerging industry. brushless motor manufacturers
